What is bituminous coal, coal tar distillation of coal products are coke and coal tar, these toxic coal tar in general how to deal with, so that non-toxic?
Physical and chemical properties: at room temperature for the black brittle block, shiny; smell, melting and easy to burn, and toxic. Is a class two flammable solid. This product is in line with the GB/T2290-94 medium temperature asphalt standardsUses: used in the manufacture of paints, electrodes, asphalt coke, oil felt, etc., can also be used as fuel and asphalt carbon black raw materialsPacking: woven bag, in bulk
All kinds of coal asphalt according to its consistency can be divided into: soft coal tar and coal tar pitch. Two kinds of soft coal asphalt is coal tar in further processing, only part of naphtha and distillate oil and viscous liquid or semi-solid product. The hard asphalt is coal tar distillate oil, fractionated in oil and heavy oil that most of the oil and anthracene oil brittle solid products. Coal tar pitch can not be directly used for road construction, coal tar pitch available for soft coal tar anthracene oil back.
Paste, to see if there is no useCoal tar pitch Coal PitchAll kinds of natural organic matter (such as coal, wood, peat or shale) in air condition, the viscous liquid, the coking distillation, called the "tar tar". Then after further processing by viscous liquid that semi-solid products called "tar". Usually the tar processing of raw materials for coal, it is referred to as the "coal tar pitch", referred to as the "pitch".
